spi/spi-xilinx: Fix spurious IRQ ACK on irq mode
commit 74346841e6f5df5f7b83d5904435d273c507dba6 upstream.
The ACK of an inexistent IRQ can trigger an spurious IRQ that breaks the
txrx logic. This has been observed on axi_quad_spi:3.2 core.
This patch only ACKs IRQs that have not been Acknowledge jet.
